I definitely liked this episode but hated half the animation. I liked the pacing and where they were going with it, though. I say do the exact same episode and double the budget. It would be the best Naruto episode we've ever seen. As far as Pain taking those hard hits: remember, Nagato's not really taking any hits. I also bet that God Mode Pain is extra beefed up defence-wise because he is the strongest and is one Nagato would not want to lose during a fight.
